AISI 4140 steel stockholders and suppliers, delivering to the whole of the UK. AISI 4140 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry. Similar to grade AISI 4130 but with a slightly higher carbon content.
Alloy Steel 4150, also sold under the name AISI/SAE 4150, is a high-carbon alloy that includes chromium, manganese, and molybdenum. This tough steel alloy offers uniform strength, wear resistance, and great hardness. It is important to note that Alloy Steel 4150 must be heat-treated to be suitable for machining.
4142 HT Turned, Ground and Polished is a chromium-molybdenun alloy steel that has been hardened to 27 to 32 Rockwell C and is ready to use while still machinable and of exceedingly high strength. The chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
The physical properties of 4140 HT greatly depend on the Heat Treating/Tempering processes that have been done to the material. If you need to meet specific physical properties for your application, please contact an Alro Sales Representative to make sure this material will meet your needs.
The have been gravitating to the so called proprietary steels listed below even tough they carry a small premium to merchant grade 4140. If you stick with 4140 I would advise using either what is referred to as Aircraft quality or one of the proprietary steels below. We switched from using AISI 4140 in our shop a number of years ago.
